Currently identified situation.
When there was an attempt to create the “internal correspondence” process at the same time, the Bitronix logs prescribed a timeout, but in fact Postgres worked, and the monitoring increased the length of the disk queue (the delay was up to 10 ms).
After 1-2 minutes, the process worked as usual and I managed to create 10 processes.
During the timeout, other processes, including service.
I ask you to correct this error.
